Speed controlled brushless diaphragm pump with PWM for vacuum and
air
The definition of diaphragm pump
A diaphragm pump (also known as a Membrane pump) is a positive
displacement pump that uses a combination of the reciprocating
action of a rubber, thermoplastic or teflon diaphragm and suitable
valves on either side of the diaphragm (check valve, butterfly
valves, flap valves, or any other form of shut-off valves) to pump
a fluid.

environmental testing requirements about Speed controlled pump
| Number | Item | Test conditions and requirements | Remarks |
| 1 | Steady-state heat and wet | 60%rh | High humidity can affect the electrical performance of the motor |
| 2 | Temperature Shock | The pump was placed at -20 ℃ environment ,after 1h immediately
placed at + 70 ℃ ± 3 ℃ environment for 1h.This is for 1cycle. After
50 cycles was returned to room temperature.0.5h later,pumping power
test is conducted. The pump should be able to work properly;
fasteners should not loose , in working condition pump’s body
should not be leakage when block pump’s outlet. | too high temperature affect pump’s parameters, life and electrical
performance |
| 3 | High temperature test | Pump is at 70 ℃ ± 3 ℃ environment for 48h. Then take it out. After
0.5hours later, at room temperature power pump. Fastening points
should be no loose. The pump can work normally. Its performance and
parameters can not change. | |
| 4 | Low temperature test | For 72 hours,pump is at -20 ℃ environment. Then take it out. Power
the pump and test it.( when testing the pump,pump’s body can not
have ice ). Fastening points should be no loose. The pump can work
normally. Its performance and parameters can not change. | In too low temperature,motor cannot be started

External PWM speed control principle
1, control board wiring diagram:
2, external use PWM speed control principle
Description: 1, the external PWM signal by a small MOS tube or
after the transistor processing, received a speed adjustment (such
as above).
2, the frequency of PWM signal can be adjusted by 100HZ-1KHZ, and
the change of speed regulation 0-6V can be realized by adjusting
the duty ratio.. When the duty cycle is 100% (i.e., total height),
the speed regulation is 0V, and the time ratio is 0 (i.e., the
total low), the speed regulation is 6V, and the speed is at full
speed.
Our company offers multiple component configurations allowing pump
to be used for either vacuum operation, pressure operation, or
alternating vacuum and pressure operations.The innovative, compact
design incorporates leading edge technologies that allow it to
operate harder, quieter and longer, reliable, highly efficient.
Its flow can deliver up to 3 L/min and 18L/M.
Usually our pump has 4 kinds of voltage:6V, 9V,12V and 24V .
When you choose pump, you can tell me the pump's voltage you need.
We can do it for you.
You can choose pump according to our model.
In addition,it can be mounted in any position.
